How to enable subframes?
https://docs.blender.org/manual/en/latest/editors/timeline.html
Here is the Blender Documentation where is explained the concept of Sub-Frames, and an image of what to do to activate it, when you check it, you will see how your actual frame field changes from a &quot;1&quot; to a &quot;1.0&quot;
You can activate it from Timeline or Graph Editor

Hope this solve your animation problems ;)
